To maximize the availability of your data in production, the appliance includes a complete end-to-end architecture for data integrity, including redundancies at every level of the stack. Key features include:
Predictive self-healing and diagnosis of all system hardware failures: CPUs, DRAM, I/O cards, disks, fans, power supplies
ZFS end-to-end data checksums of all data and metadata, protecting data throughout the stack
RAID-6 (double- and triple-parity) and optional RAID-6 across disk shelves
Active-active clustering for high availability (See Appliance Cluster Configuration)
Link aggregations and IP multipathing for network failure protection (See Network Configuration)
I/O Multipathing between the controller and disk shelves
Integrated software restart of all system software services (See Appliance Services)
Phone Home of telemetry for all software and hardware issues (See Phone Home Configuration)
Lights-out Management of each system for remote power control and console access
